patches module in matplotlib allows us add shapes like rectangle on top of a plot. Let us load patches as mpatches. We can add rectangle by using Rectangle() function in patches module. The Rectangle function takes the location/size of the rectangle you need, left position, bottom location, and width & height.

  1. Choose arbitrary points A and B in the plane and draw segment AB.
  2. Raise a perpendicular m to AB at A.
  3. Raise a perpendicular n to AB at B.
  4. Choose an arbitrary point C on line n.
  5. Drop a perpendicular from point C to line m.
  6. Then quadrilateral ABCD is a rectangle.

A golden rectangle can be constructed with only a straightedge and compass in four simple steps:

  1. Draw a simple square.
  2. Draw a line from the midpoint of one side of the square to an opposite corner.
  3. Use that line as the radius to draw an arc that defines the height of the rectangle.
  4. Complete the golden rectangle.
